Specific embodiment
The air curtain unit in the band bilayer air channel of the utility model implementation method 1 as shown in Figure 1, including:Housing 2, housing Working chamber and air channel are inside set to, working chamber is located at the top in air channel, and working chamber top is provided with blower fan 1, and the bottom of housing 2 is provided with air-out Mouth 4, sets dividing plate 9 in the working chamber, dividing plate 9 is extended in air channel, and working chamber is divided into convection cavity 11 and vented cavity by dividing plate 9 12, air channel is divided into hot air duct 5 and cold wind air channel 10 by dividing plate 9, and convection cavity 11 is connected with hot air duct 5, the He of vented cavity 12 Cold wind air channel 10 is connected, and heat exchange core body 8 is provided with convection cavity 11.The heat exchange core body 8 is copper pipe aluminum fin heat exchanger, heat exchange core Body 8 by water inlet 3 and water return outlet 7 realize heat transferring medium in its internal circulation.The duct cross-section is isosceles trapezoid, can be by After the air of inspiration enclosure interior under the forced convertion of blower fan 1 is acted on carries out decompression acceleration interior is sent to through air outlet 4.Housing 2 Top is provided with wiring hole, and electric-controlled box 6 is housed at wiring hole, and blower fan 1 is connected by wire with electric-controlled box 6, and electric-controlled box 6 is used to control The start and stop of blower fan processed 1 and rotating speed.The top of housing 2 is provided with three blower fans 1.The top of the blower fan 1 is provided with screen pack, and screen pack is used for The particles such as the dust of the suction hollow gas of unit are filtered, to purify the cold-hot wind of blowout.
The air curtain unit in the band bilayer air channel of the utility model implementation method 2 as shown in Figure 2, including:Housing, and housing Including:Main case and air channel shell, the main case bottom of air channel shell connection is working chamber in main case, is air channel, work in the shell of air channel Make chamber to be connected with air channel, working chamber is provided with blower fan, air channel bottom is provided with air outlet, dividing plate is set in the working chamber, and dividing plate prolongs Extend in air channel, working chamber is divided into convection cavity and vented cavity by dividing plate, air channel is divided into hot air duct and cold wind wind by dividing plate Road, convection cavity is connected with hot air duct, and vented cavity is connected with cold wind air channel, and heat exchange core body is provided with convection cavity.The heat exchange core Body be copper pipe aluminum fin heat exchanger, heat exchange core body by water inlet and water return outlet realize heat transferring medium in its internal circulation.Institute Duct cross-section is stated for right-angled trapezium, after the air of inspiration enclosure interior carries out decompression acceleration under being acted in blower fan forced convertion Interior is sent to through air outlet.Housing top is provided with wiring hole, and electric-controlled box is housed at wiring hole, and blower fan passes through wire and electric-controlled box phase Connection, electric-controlled box is used to control start and stop and the rotating speed of blower fan.Housing upper is provided with three blower fans.The blower fan top is provided with filtering Net, screen pack is used to filter the particles such as the dust of the suction hollow gas of unit, to purify the cold-hot wind of blowout.
Blower fan in implementation method of the present utility model can set a blower fan, or two according to burden requirement and field condition Individual blower fan, or more blower fan.
The utility model need to be arranged on around architecture indoor gate, can be horizontally mounted as shown in Figure 3 or right angle setting such as Shown in Fig. 4.As a example by being horizontally mounted, in practical work process, work of the room air in the forced convertion of the blower fan of housing upper The working chamber of enclosure interior is entered under, due to the centrifugation of dividing plate, the air of suction is divided into two parts, part warp Heat exchange core body is crossed, interior is sent to after internal heat transferring medium heat exchange with it.And during air-supply, due to trapezoidal air channel Effect, the decompression for realizing hot-air accelerates to blow.There is heat exchange in another part air, without heat exchange core body directly via interior Portion cold wind air channel decompression uniform feeding interior after accelerating.Due to cold air, density is larger compared with hot-air, it is possible to achieve farther The air-supply of distance.Cold air mixes in air outlet with hot-air, and hot-air can be induced to realize more air-supply at a distance.Cold and hot sky Gas forms double-deck air curtain in gate side, and the exchange of cold and hot amount inside and outside air lock reduces the quantity of heating equipment near gate, Improve gate environmental amenity degree nearby.Meanwhile, when outside work personnel get in, due to first passing through cold air, by Overfire air, temperature rate of change is low, and personnel will not be made to produce discomfort.
To the disclosed embodiments described above, those skilled in the art are enable to realize or new using this use Type, the various modifications to the present embodiment are it will be apparent that generic principles defined herein for those skilled in the art Can in other embodiments be realized in the case where spirit or scope of the present utility model are not departed from.Therefore, every and this reality The same or analogous technical scheme of example is applied, is all fallen within protection domain of the present utility model.
